Bend your knees and push your butt back toward your heels, and then explode from that position back to a high plank and immediately bend your elbows and bring your chest toward the ground to do a push-up. As you bend your elbows and lower toward the ground, your elbows should be at about a 45-degree angle to your body (though you can make adjustments based on what feels best for your shoulders).

If you're ready to move on from classic Bulgarian split squats, Swan's amped-up variation gets your upper body in on the action for a true total-body exercise. "This combination move works your legs, butt, chest, back, arms, and core," she says. "And it not only hits all the major muscle groups—it also lets you work on balance." Give it a shot and you'll see why.

Kick your leg up as close to your elbow as you can and then lower it back down and place your foot back on the ground. Once your foot is back down, repeat the push up then kick the other leg out to the side toward your elbow. Keep your leg as straight as you can as you kick it out. Place your foot back and repeat the push up before repeating on the first side.
Exercise increases energy and vitality feelings. Sedentary individuals often complain of being too tired to work out. Ironically, exercise improves people's capacity for work so that people who exercise on a regular basis actually have more energy and greater strength and endurance for daily activities than do their sedentary peers. The feeling of increased energy, and vitality is one of the first things people tend to notice a few weeks after beginning to working out on a regular basis.
Don’t be afraid of weights. After all, muscle burns more calories than fat. Do you want to know how to lose arm fat? Start with dumbbells, says Dede Lagree, who has worked with Angel Elsa Hosk and is the owner and head trainer at Lagree Fitness Studio. For Lagree’s arm-toning workout, choose a pair of dumbbells that you can safely lift at least 20 times. But pick a weight that challenges you: Your arms should feel that 20th rep! Don’t have dumbbells? Substitute soup cans or water bottles, Lagree says. Check out all the great body changes you get from lifting.
Chili has a chemical known as capsaicin that helps in burning fat and increases the metabolic rate (3). Capsaicin works by increasing the levels of norepinephrine, which is a neurotransmitter that helps in the burning of fat. Therefore, an increased level of norepinephrine leads to weight loss. Incorporate chili in your daily diet to see the results for yourself.
Before we look at what we can do for reducing arm fat, let’s be sure to understand the most common misconception about weight loss that is still floating around out there: spot-reducing. Science says you can’t spot reduce body fat. That means you can’t pick a spot on your body and exercise the fat away. You see, you store fat cells all over your body. Where your fat cells happen to be more concentrated is often a genetic predisposition. Having more fat on your arms doesn’t mean you can lose the fat directly from your arms alone. It means you have to first lose body fat all over, and then work on specifically strengthening your arms to tone them the way you wish.

The workout includes a dynamic warm-up to get your blood flowing and prep your body for the rest of the work ahead, and a cool-down to help you slow back down and wrap it all up. If you want to make the workout more challenging—maybe you've done it a handful of times and are ready to turn things up a notch—add weights to the lunge and squat movements. You can also, like Sims said, add another round of the main strength circuit.

Exhale as you raise your body back to the starting position. Do this gently and slowly so you do not hyperextend your shoulders. Be sure to retract your shoulder blades and keep your shoulders square and stabilized (not rolled forward or up). As soon as it is difficult to hold your shoulders still and pulled back, stop the range of motion. This is 1 rep. Repeat this exercise for 2 sets of 10 reps. You should feel your tricep muscles working after 2 sets of this exercise.
Take up rowing or kayaking. Doing a sport that activates your arm muscles will help you to tone your arm muscles. Consider taking up an arm focused hobby like rowing or kayaking, which requires arm strength and good core engagement. You can start by doing the rowing machine at the gym and then work up to taking classes in rowing or kayaking. You can also join a recreational rowing team in your area to get better at rowing and be more active on a weekly basis.
Sweating it out in the gym is a known de-stressor. Harvard Medical School has shown that aerobic exercise helps curb stress hormones like cortisol and adrenaline (as long as you're not overdoing it), while also flooding your system with feel-good endorphins. It also ups the calming, good-mood brain chemicals serotonin and dopamine. So while exercise itself is actually putting low-level physical stress on the body, it can be pretty mentally relaxing.
Those buff lab rats might be smarter than we think. Various studies on mice and men have shown that cardiovascular exercise can create new brain cells (aka neurogenesis) and improve overall brain performance Aerobic exercise is the critical variable in an enriched environment that increases hippocampal neurogenesis and water maze learning in male C57BL/6J mice. Mustroph ML, Chen S, Desai SC, Cay EB, DeYoung EK, Rhodes JS. Neuroscience Program, The Beckman Institute for Advanced Science and Technology, University of Illinois at Urbana-Champaign, Urbana, IL, USA. Neuroscience. 2012 September 6;219:62-71. Aerobic exercise improves hippocampal function and increases BDNF in the serum of young adult males. Griffin EW, Mullally S, Foley C, Warmington SA, O’Mara SM, Kelly AM. Department of Physiology, School of Medicine, University of Dublin, Trinity College, Dublin, Ireland. Physiology & Behavior. 2011 October 24;104(5):934-41.. Ready to apply for a Nobel Prize? Studies suggest that a tough workout increases levels of a brain-derived protein (known as BDNF) in the body, believed to help with decision making, higher thinking, and learning. Smarty (spandex) pants, indeed.
